Then God said, “Shall I keep back from Abraham what I’m about to do? Abraham is going to become a large and strong nation; all the nations of the world are going to find themselves blessed through him. Yes, I’ve settled on him as the one to train his children and future family to observe God ’s way of life, live kindly and generously and fairly, so that God can complete in Abraham what he promised him.”
Genesis 18:17-19 MSG
When God chose you to be His and your responded, it is settled. Get that! It is settled. He selected and settled on you. There is no more decison to be made. Walk it out and enjoy the settledness.
